53,713 separate polygons classify the global ocean floor into 11 distinct 'seascapes' based on six biophysical variables. This dataset, hosted by the Australian Ocean Data Network, was created using a multivariate statistical method to identify candidate sites for high seas marine protected areas. The analysis uses GIS tools to map seascape and geomorphic heterogeneity, aiming to provide an unbiased basis for conservation planning.
Use Cases
- Identifying candidate sites for marine protected areas based on seascape heterogeneity maps.
- Classifying benthic bioregions using multivariate analysis of six biophysical variables.
- Validating ocean floor classifications by comparing seascapes with existing geomorphology maps.
- Supporting stakeholder communication with computer-aided, less subjective mapping outputs.
Strengths
- Derived from a multivariate statistical analysis of six global biophysical variables.
- Contains 53,713 separate polygons organized into 11 distinct seascape categories.
- Validation performed via comparison with an existing seafloor geomorphology map.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic or methodological bias inherent to the source platform and analysis.
